Platonic Hylomorphism

Hylomorphism is almost universally claimed to be a staple doctrine of Aristotle. In this paper, I discuss a wide range of texts from the dialogues of Plato that straightforwardly display hylomorphism. Both Plato and Aristotle rest their cognitive realism on their hylomorphism. The crucial difference between Aristotle’s hylomorphism and Plato’s is that Aristotle believes that hylomorphism supports and is supported by essentialism whereas Plato does not. Plotinus presents arguments against Aristotle’s essentialism at the same time as he defends Platonic hylomorphism and his cognitive realism.
